You already have the hardware: Amazon.com: Intel Core i7 6700K 4.00 GHz Unlocked Quad Core Skylake Desktop Processor, Socket LGA 1151 [BX80662I76700K]: Computers & Accessories is your best option at pricepoint. It is also a bit faster than the 4790k. As eagles stated, it does not make much sense for you to completely switch platforms (mobo, ram, etc) when all you really need to do is upgrade the CPU.
Here is a comparison:
Intel Core i7 6700K vs 4790K
